Varietal denomination: ‘Angel Rouge’.

CROSS REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit of priority from Japanese Plant Variety Protection Application No. 31958, filed Mar. 24, 2017, which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct Bidens laevis plant known by the varietal name ‘Angel Rouge’. The new variety is the result of a planned breeding program with the purposes of providing Bidens plants with a red flower color and a compact growth habit. The breeding process leading up to ‘Angel Rouge’ began in 2012 from the applicant's proprietary collection of Bidens plants. Ultimately, ‘Angel Rouge’ is the result of a 2014 cross between Bidens L. varieties referred to as BR5-3 (female parent, unpatented) and Nunca Y-1 (male parent, unpatented) and was discovered in 2015 in Aichi Prefecture, Japan. The first asexual reproduction of the new variety was conducted by cuttings in 2016 in Aichi Prefecture, Japan. ‘Angel Rouge’ has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive asexual propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

When ‘Angel Rouge’ is compared to Bidens L. ‘Angel Cheek’ (unpatented), both varieties exhibit a compact growth habit and orange-red colored ray florets. However, the ray florets of ‘Angel Rouge’ have a solid and dark, orange-red colored upper surface, while the ray florets of ‘Angel Cheek’ have a lighter, primary orange-red color and a secondary orange-yellow color present at the upper surface base and tip. Further, ‘Angel Rouge’ exhibits no to less anthocyanin stem coloration when compared to ‘Angel Cheek’, which has weak anthocyanin stem coloration. Additionally, ‘Angel Rouge’ has an earlier time of flowering than ‘Angel Cheek’.

The following traits distinguish ‘Angel Rouge’ as a new and distinct cultivar from other Bidens varieties known to the breeder:

-   -   1. Compact growth habit;     -   2. Short plant height;     -   3. Absent or very weak anthocyanin stem coloration;     -   4. Pinnate leaves;     -   5. Medium-sized leaves;     -   6. No leaf variegation present;     -   7. Single inflorescences (less than 8 ray florets);     -   8. Medium inflorescence diameter;     -   9. Medium ray floret length and width;     -   10. Shallow ray floret apex incisions;     -   11. Solid and dark, orange-red colored upper surface of ray         florets;     -   12. Early time of flowering; and     -   13. Continuous flowering habit.
